Disadvantages of OTP
- To receive an OTP, users must have access to a device and a network connection. If a user’s device is lost or stolen, or the network is unavailable, the user may not be able to access the OTP and may be locked out of their account.
- OTP is only valid for a limited time usually ranging from 30 seconds to a few minutes. If a user does not enter the OTP within the specified time frame they may need to request a new OTP, which can be inconvenient.
What is One Time Password?
OTP stands for “One-Time Password”, which is also known as One-Time PIN or Dynamic Password. It is a password for a computer or digital device that is used only once for one session or one transaction.
OTP or One Time Password is a 4 or 6-digit security code. For example, when you transact online or shop online on an e-commerce website, you will receive a security code via SMS from the bank on your registered mobile number after filling in the banking details. This security code is called OTP. This OTP can be used only once for any session or transaction. That is, once used this code cannot be used again. So you will need a new OTP to complete a new session or transaction.
OTP is a mechanism that provides safe entrance or safe logging in on any network or service. Every time it’s a unique code generated for accessing the network or service securely. It has a unique specialty that does not work again and again, it changes after each usage session & is a different and unique code each and every time.
